NOTE: If you want
to
copy a
file
from one diskette
to
another, you cannot use the
COPY command. Instead, use the copy program on the TestlDemo diskette or the
DOS Shell (see Chapter 4).
CONCAT
The CONCAT command allows you
to
concatenate (combine) two sequential files.
FORMAT FOR THE CONCAT COMMAND
CONCAT [Ddrive#
,]
"add
file" TO [Ddrive#,] "master file" [,Udevice#]
Where the optional
drive#
would be 0
in
both cases. The old "master file"
is
deleted and replaced with a new "master file" which
is
the concatenation
of
the old
"master file" and
"add
file" .
NOTE: The length
of
a command string (command and filenames)
is
limited to
41
characters.
SCRATCH
The SCRATCH command allows you
to
erase unwanted programs and files from
your diskettes, and free
up
the space they occupied for use
by
other files and programs.
It
can be used
to
erase either a single file, or several files
at
once via pattern-matching.
FORMAT FOR THE SCRATCH COMMAND
SCRATCH
"pattern"
[,Ddrive#] [, Udevice#]
Where,
"pattern"
is
any valid
file
name or pattern-matching character.
You will be asked
as
a precaution:
ARE YOU SURE? •
If you ARE sure, simply press Y and RETURN. If not, press RETURN alone or type any
other answer, and the command will be canceled.
